We knew things were really bad at BlackBerry. Now we know they’re really, really bad. Rumours are swirling that the faltering tech giant will cull up to 40 per cent of its workforce by Christmas, which would bring its employee count below 8,000. (To compare, two years ago, the company had more than 17,000 people.) BlackBerry wouldn’t comment on the story, but sources say the cuts will come in waves, affect all departments and hit BlackBerry’s Waterloo headquarters the hardest. The extra twist of the knife: news of the layoffs broke the same day that the company unveiled the BlackBerry Z30. It has the largest screen and longest battery life of any BlackBerry to date—not that anyone noticed. [Wall Street Journal]
